Hoped i read description correctly. Have 1966 M20 4 speed. Is cross the country from me, at the spa of one of the best retired specialist's shop in the USA. Kit arrived at his place. He checked it out. Gave approval and took trans apart. Found nothing inside trans to worry about it. After inspection, used this kit to put all back together. He's been rebuilding transmissions for over 55 yrs. Said was surprised such a good gasket was still available. Most of what people bring with them when drop of trans, are garbage. Take it from Kip, this is NOT a rebuild kit, IT IS A VERY GOOD GASKET AND SEAL KIT FROM VITAL PARTS ON AMAZON. No idea what others on Amazon are selling, Got mine from VITAL PARTS, right here on Amazon . Price was reasonable and prompt service.

All components fit my 1969 660 case M-21 Muncie just fine. The Italian bearings are the best for these transmissions but just my opinion. Haven’t installed it in car yet but no leaks so far!
